Unfortunately, Mother Nature threw another slide job at the Mason City Motor Speedway and the show slated for Sunday, May 24, is rained out.

But there is a silver lining.

Tonight’s Mayhem! in Mason City is postponed and will now happen Thursday, June 18, with the fire-breathing Modifieds of the Summit USMTS National Championship fueled by Casey's taking center stage.

The Christie Door Company Iron Man Challenge built by Medieval Chassis featuring USRA Stock Cars and USRA B-Mods will also be in action along with USRA Hobby Stocks and USRA Tuners.

Stay tuned... More details to be announced.
